This is my first time playing in the WA. Really excited and looking forward to it.
I’m a gross division player, and have played in many tournaments around the country. Usually groups are paired based on score for the last couple of rounds. That said, I do understand this is an unusual format with so many players to manage. I would think the organizers would have something like “sub committee chairman” for each division and organize the tee times/groupings appropriately. Tee times can be broadcast by e-mail, group text, or even have players call the pro shop of the course they will be playing to find their tee times.
I trust they know what they’re doing though or they wouldn’t have 3500 people sign up, with many repeat customers. LOL!!
Good luck and have fun!
